Hey everyone, I have a 870 images from 29 different classes and each class has 30 images in sequential number from 1 to 30, following this pattern NameOfTheImage_1-30. What I want to do is to open and then convert all of the images, automatically one by one, into grayscale. Can you help me with that? The codes from here are somehow usefull but not for my case (I think).

From my understanding you want to open multiple images from multiple classes. Here is the code which might help you:
for class = 1:29
for a = 1:30
filename = ['Parent folder/class' num2str(class,'%d') '/NameofTheImage_' num2str(a,'%d') '.PNG'];
img{class,a} = imread(filename);
% Processing
end
end

Img = dir('*.png') ; % give your extension of images
N = length(Img) ;
for i = 1:N
thisImg = Img(i).name ;
I = imread(thisImg) ;
Ig = rgb2gray(I) ;
% do what you want
end
